Abstract: 9961. United Cigarette Machine Co., [Ludington, F. J.]. May 30. Cigarette-making machines.-Relates to machines for the manufacture of all-tobacco cigarettes, and comprises improvements in the wrapper-cutting, wrapper holding and conveying, and wrapperpasting apparatus, the filler forming and rolling appliances being of any suitable character. Fig. 1 shows the machine in plan view. The wrapper is cut at the position marked A, and is pasted and supplied to the rolling apron at B. Fig. 6 shows in section the punch for cutting the wrappers from the tobacco leaf. The rectangular punch A, carried by a cam-actuated plunger E, co-operates with the die V located in the table V<1>. Within the punch is a cam-actuated plunger or clamp Q, provided with four longitudinal ribs Q<1> faced with thick rubber strips Q<3>, which serve to hold the tobacco leaf upon the carrier or platen W. The punch is surrounded by a fixed stripper U, which serves to free it from adhering leaf. After a wrapper has been cut, the platen W descends, followed by the clamp Q. Gripping-fingers b, Fig. 2, carried by an arm b<2>, now enter between the ribs C', and the fingers are spring-pressed upon the wrapper. The clamp Q returns to its normal position within the punch A. The platen is carried by an arm W<1> secured to a shaft W<3> capable of a limited rocking movement in the head X of a vertical shaft X<1>. The shaft X<1> is movable vertically by means of a cam-actuated lever, and is also adapted to turn through a rightangle by means of a pinion engaging with a camactuated rack Z<2>. Fig. 2 shows the platen after it has swung through a right-angle towards the pasting and wrapping devices, it being then at the rear of and no longer beneath the table V<1>. The arm W<1> is tilted forward to bring the platen into the position shown in Fig. 14 by means of a cam-actuated lever a<2>, link a', and arm a. The gripper-carrying arm b<2> is tensioned towards the platen by a spring on the rod c<1>, Fig. 2. The arm b<2> is pivoted about a stud b<4> on a sleeve c sliding on the rod c', and bears a stud d. In the position shown in dotted lines in Fig. 2, i.e., when the platen is beneath the punch, the stud b<4> engages in a horizontal slot in a horizontallymoving cam-actuated slide, and the stud d engages in a vertical slot in the same slide. A movement of the slide to the left swings the gripper clear of the platen about the stud b<4>, and a slight descent of the platen, after the stud b<4> has engaged in the horizontal slot, enables the gripper to return without coming in contact with the wrapper, the platen afterwards rising sufficiently to grip the wrapper between it and the fingers b. As the platen comes into the position shown in Fig. 14, a cam surface on the sleeve c comes in contact with a fixed cam so as to raise the gripping-fingers clear of the platen and release the wrapper. The pasting of the rear edge of the wrapper is effected as follows :-The paste is contained in a reservoir n, Fig. 14, provided with a feed-roll l. A brush h<1>, carried by a sleeve h', is adapted to make a single revolution so as to convey paste from the roll l to the wrapping- leaf, the brush being shown in Fig. 14 in the act of pasting the leaf. A shaft h<5> rotates continuously within the sleeve h<4>, and drives it by means of a pair of discs separated by a friction washer whenever a stop is removed from the path of a pin carried by a disc on the sleeve h<4>. The stop is withdrawn for a moment and then returned to its place, a single revolution of the brush being thus produced. The paste-roll l is rotated by ratchet mechanism from the shaft h<5>. The pasting of the wrapper is effected after the forward edge has been caught by the rolling- apron o'.
